I. Basic Concepts

Activity I.1

In this activity you will explore previous knowledge about statistics basic concepts

1.- Reflecto n the following questions

a) What is statistics?

R= is a science that facilitates the solution of problems from which we need to know some characteristics about the behavior of some event, characteristics that allow us to know or to improve the knowledge of that event

b) Do you know any report that uses statistics?

Yes, sales report some Or INEGI census reports.

c) what means of communication uses statistics frequently?

mainly on TV,

d) how do you identify statistics information in an article?

Because aroja data by using tables or graphs, with different variables.

5.-research about the following concepts.

Statistics: is a science that facilitates the solution of problems from which we need to know some characteristics about the behavior of some event, characteristics that allow us to know or to improve the knowledge of that event.

Descriptive Statistics: is in charge of the collection, organization, presentation, and analysis of a population.

Inferential Statistics: is in charge to analyze information presented by the descriptive statistics through techniques that help us to know, with certain confidence, to the population, that allow us to take decisions.

Population:to the set, well defined, of all the individuals, where it is observed or will be observed certain characteristic.

Simple: is a subset of a population that tries to réflex the characteristics of the population the best as posible.

Individual: to the element of the population or of the simple that has the information about what it is studied.

Variable: A variable which is characteristic to be measured in different individuals are capable of adopting different values.

Quantitative variable: when in the measuring it is assigned numbers.

Qualitative variable: when only attributes or categories can be assigned.

Data: the value that is obtained when performing the measurement of the characteristic of the variable in study.

Qualitative data: the in this case, it is obtained when qualifying the characteristic as the gender, the marital status or the máximum level of studies.

Quantitative data: as the values obtained when measuring the weight, the height, the temperatura, the number of children.

Continuous variable: if when performing the measurement, the variable can take as value any real number between two given values (inside an interval)

Discrete variable: the variable can only take as values whole numbers

Sclae: zero or initial point is not the unique, is rather a reference point.

Nominal scale: is associated to qualitative variables and it is denominated in this way, if you can not do arithmetic operations among their values, since they are only tags.

Ordinal scale: is for the values of the variables that have an order, with a specific level, but you can not do arithmetic operation between those values.

Interval scale: there is an order between the values of the variable and there is also a notion of the distance, although it is not posible to perform operations.

Ratio scale: the magnitude has a physical sense: here exists the absolute zero, which makes reference that the amount does not exist in that value.

Survey: consists in collecting the data through the use of questionnaires or interviews.

Experiment: is a procedure used in the scientific investigation to obtain information that permits to know the behavior of some process.

Documental research: is a procedure to obtain data through the query of written information and concentrated in
